PCBA processing

PCBA processing business process


1. The customer proposes his own PCBA processing requirements and provides the data files required for processing.

2. The company analyzes customer requirements and data files.

3. The company confirms the processing plan according to the customer's request and quotes it to the customer.

4. Purchasing the required materials in accordance with the requirements of the customers in accordance with the processing requirements.

5. Production prototypes, testing, feedback to customers.

6. Arrange mass production.

PCBA processing process



Printed solder paste

The squeegee pushes the solder paste along the surface of the stencil. When the solder paste reaches an open area of the stencil, the downward pressure exerted by the squeegee forces the solder paste through the stencil opening area onto the PCB board.

2. Apply adhesive

Double-sided assembly of the PCB board To prevent the bottom surface mounting components or the double-sided reflow soldering during wave soldering, the bottom large integrated circuit device is melted and dropped, and the adhesive is required to stick the components. In addition, in order to prevent the positional movement of the heavier components when the PCB is transported, it is also necessary to stick it with an adhesive.

3. Component placement

The process is to use an automated placement machine to pick up surface mount components from the feeder and accurately place them on the printed PCB board.

4. Pre-weld and post-weld inspection

Before components pass through reflow soldering, it is necessary to carefully check whether the component is mounted properly and the position is not offset. After the welding is completed, the solder joints and other quality defects need to be inspected before the assembly enters the next process step.

5. Reflow welding will

After the component is placed on the solder, the solder on the pad is melted using a thermal-convection flow soldering process to form the mechanical and electrical interconnection between the component leads and the pad.

6. Component insertion

For surface mounted components such as through-hole insertion components and certain machines, such as some cartridge electrolytic capacitors, connectors, push button switches, and metal end electrode elements (MELF), for manual insertion or use Automatic insertion equipment for component insertion.

7. Wave soldering

Wave soldering is mainly used to weld through-hole insertion components. When the PCB passes over the crest, the solder wets the leads that have leaked from the bottom of the PCB, and the solder is attracted into the plated sockets, forming a tight interconnection of components and pads.

8. Cleaning

Optional process. When the solder paste contains organic components such as rosin and lipids, the residues formed after the solder paste is combined with the water in the atmosphere have strong chemical corrosiveness, and remaining on the PCB board will hinder the reliability of the circuit connection. Therefore, these chemicals must be thoroughly washed away.

9. Maintenance

This is an off-line process that aims to economically repair defective solder joints or replace defective components. Maintenance can basically be divided into three kinds of repair welding, heavy industry and repair.

10. Electrical testing

Electrical testing mainly includes on-line testing and functional testing. On-line testing checks the connection of each individual component and test circuit is good. Functional testing determines whether the entire circuit can achieve a predetermined function by simulating the working environment of the circuit.

11. Quality Management

Quality management includes quality control within the production line and product quality assurance before delivery to customers. It is mainly to check the process control status of defective products and feedback products and ensure the quality indicators of the products to meet the requirements of customers.

12. Packaging and sampling inspection

Finally, the components are packaged and sampled after packaging to ensure that the products to be delivered to customers are of high quality.
